There is a handle below the driver's side A-pillar with an icon indicating "Open the engine hood." Pull it firmly, and you will hear a "pop" sound as the engine hood lifts slightly. Lift the hood slightly, and at the front end inside the hood, there is a hidden switch. Push it to the left to fully open the hood. Functions of the front hood: 1. Airflow guidance. For high-speed moving objects in the air, the air resistance and turbulence generated around the object directly affect its trajectory and speed. The shape of the hood can effectively adjust the direction of airflow relative to the car's movement and the resistance it generates, reducing the impact of airflow on the car. Through guidance, air resistance can be decomposed into beneficial forces, increasing the front tires' grip on the ground, which enhances driving stability. The streamlined design of the hood is largely based on this principle. 2. Protection for the engine and surrounding components. Under the hood lie critical components of the car, including the engine, electrical circuits, fuel system, braking system, and transmission system, all of which are vital to the vehicle. By enhancing the hood's strength and structure, it effectively guards against impacts, corrosion, rain, and electrical interference, ensuring the vehicle operates normally. 3. Assisting driver visibility. During driving, the driver's ability to correctly judge road conditions and the environment ahead depends significantly on the reflection of natural light and forward visibility. The hood's shape can effectively adjust the direction and form of reflected light, reducing its impact on the driver. 4. Accident prevention. The engine operates in a high-temperature, high-pressure, and flammable environment, where overheating or accidental damage to components can lead to explosions, fires, or leaks. The hood acts as a protective shield, effectively blocking damage caused by explosions, isolating air, and preventing the spread of flames, thereby reducing the risk and extent of fire damage.
As a driver who frequently gets behind the wheel, I'd like to explain what 4WS means in cars. 4WS stands for Four-Wheel Steering in English, which refers to four-wheel steering technology. This means all four wheels of the car can steer independently, unlike traditional vehicles where only the front wheels steer. This technology makes the vehicle more agile and stable during turns, especially during sharp turns or high-speed lane changes. I think its main advantage is reducing the turning radius—for example, making U-turns easier in tight parking lots and lowering the risk of scraping. Additionally, at high speeds, the rear wheels also steer slightly, improving handling and traction for a smoother, more comfortable drive. However, there are downsides, like higher costs and potentially more complex maintenance. Overall, if you care about driving experience, 4WS is a pretty cool upgrade.
